Abstract: This paper focuses on the analysis of the starting
capacity and temperature field of the line-start permanent magnet
synchronous motor with the anti-salient pole. In order to further improve
the performance of the traditional LSPMSM, the magnet structure is optimized
to get better starting properties. Further, the models have been applied to
investigate the impact of anti-salient pole on the efficiency and power
factor. The temperature field of proposed motor with anti-salient pole has
been compared to the traditional LSPMSM with classical rotor. Prototype
machines with the two rotors have been built and tested. Experimental
results are compared in terms of starting, efficiency, power factor and
temperature. It has been found that anti-salient pole improves the overall
properties of the LSPMSM.
